Another form of "Own3d" except on a higher level. This comes from super smash bros. melee when you throw a Poke'ball and this stupid duck comes out and murders your ass with a grid. We couldn't make any sense of it so it became a term.

"Oh man while Cassious wasn't looking i put a fat turd in his taco!"
"Oh snap, hes 'bout to get Internet Ducked!"
